Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Efficient and Durable Sulfion Oxidation Coupled With Hydrogen Production via Cu@Cu2S Heterostructured Nanowires

Carbon Energy, EarlyView.
We present a facile and liquid‐phase approach to synthesize Cu@Cu2S core‐shell heterostructure nanowires derived from copper nanowires at room temperature for robust sulfide oxidation reaction (SOR)‐assisted H2 generation. The Cu@Cu2S core‐shell heterostructure nanowires exhibit superior SOR activity with an ultralow potential of 0.3 V (vs.

Harnessing Acoustic Cavitation Energy for the Selective Degradation of Impurities in Glucose Syrup

Chemistry – A European Journal, EarlyView.
The energy released during the implosion of acoustic cavitation bubbles can be harnessed and selectively transferred to a target solute, enabling its specific decomposition without degrading other solutes present in the solution. This proof of concept was demonstrated in the degradation of impurities present in trace amount in glucose syrup.

Detection of 5-hydroxymethylfurfural and furfural in the aerosol of electronic cigarettes [PDF]

Tobacco Control, 2016
The wide availability of sweet flavours has been hypothesised as a factor in the popularity of electronic cigarette (ECIG), especially among youth. Saccharides, which are commonly used to impart a sweet flavour to ECIG liquids, thermally degrade to produce toxic compounds, like aldehydes and furans.
